H O RSESHOE-CALK.

Specification of Letters Patent.

.tatented May 22, 1906.

To all whom it may concern- Be it known that I, OTTO J. HENNEBEUL,

a citizen or the United States, and a resident of Wilkes-Barre, in the county of Luzerne and State of Pennsylvania, have invented a new and Improved Horseshoe and Calk, of which the following is a full, clear, and exact description. The purpose of the invention is to provide a continuous and marginal calk and a construction of horseshoe to which the calk is adapted and to so form said factors that they will be simple and economic and. so that the calk can be readily applied to the. shoe or removed therefrom by any one of ordinary intelligence.

Another purpose of the invention is to provide a form of horseshoe-calk which will wear for a maximum length of time and remain substantially sharp until Worn even with the surface of the'shoe to which it is applied, and, furthermore, to provide a calk which is adjusted to the extreme outer edge of the shoe,

thereby giving the horse a perfect balance as well as a level bearing, tending largely to insure the horse against lameness and enabling it to travel with greater case than usual.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in. which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a plan view of the improved shoe and a calk applied, one or the heel-locks being in section. Fig. 2- is a bottom plan view of the improved shoe and applied calk, a part of one heel portion of the calk being broken away. Fig. 3 is a side elevation of the improved shoe and attached calk. Fig. 4 is a transverse central section taken practically on the line 4 4 of Fig. 2-. Fig. 5 is a transverse section taken practically on the line 5 5 of Fig. 1. Fig. 6 is a transverse section taken substantially on the line 6 6 of Fig. 2. Fig. 7 is a bottom plan view of a slightly-modified form of the shoe and applied calk, and Fig. 8 is a transverse section taken practically on the line 8 8 of Fig. 7.

The horseshoe A, with but a few exceptions, is of the customary type, being provided with the usualtoe-clip 10 and nail-holes 11. The shoe differs from the ordinary shoe, however, in that a centrally-located-heel slot 12 is made in each end of the shoe, as is shown in Fig. 1, and a marginal recess 13 is produced in its under face at its outer edge, which recess leaves the margin of the shoe at a point near the heel, as shown at 20 in Figs. 3 and 7, and is continued along the under face of the shoe to the heel-slots 12 in the form of grooves 14, as is clearly shown in Figs. 2 and 6. At each side of the toe-clip 10 avertical recess 15 is made in the outer face of the shoe, extending from the recess 13, with which it connects through the upper face of the shoe, as is shown in Fig. 1.

The calk B fits around the shoe at its outer face and extends continuously or with an unbroken body portion from one end of the shoe to the other. The calk is made of steel of any desired thickness, but sufficiently thin to permit it being slightly sprung at its ends. The inner face of the calk B tapers from the top downward to the bottom, being therefore more or less wedge-shaped or thinner at the bottom than at the top, so that as the calk wears it still presents an edge capable of effective service on a slippery or smooth surface.

The call: can be of any desired depth or width; but it is at all times much wider than the depth of the shoe, and a number of re cesses 16 are produced in the bottom edge of the calk, forming a series of quite wide teeth 17. Elongated openings 18 are made in the calk about opposite the central portions of the teeth 17 and between the edges of said teeth and the upper edge of the calk. These openings 18 are provided in order that when the teeth 17 wear down to the line of said openings new teeth will be formed. In the further construction of the calk lugs 19 are formed at the front apertured to receive screws 19 and when the calk is in place on the shoe said lugs enter and fit snugly in the front recesses 15 in the shoe. At each end of the calk upwardly-extending lugs 20 are pro duced, adapted to enter the slots 12 in the ends of the shoe. The said lugs are provided with forwardly-extending heads 21, which when the calk is placed in position on the shoe extend over the upper face of the shoe at the forward ends of the slots 12. The calk is substantially in the shape of the shoe to which it is to be fitted, and in fitting a call: to a shoe the lugs 20 are made to enter the heel-slots 12 in the ends of the shoe, the ends of the calk being sprung inward for that purpose, and consequently those portions of the IIO calk adjacent to its ends will be entered in the grooves 14, while the remaining portion of the calk at its upper edge is fitted in the marginal recess 13 and as the calk is thus fitted to the said recess the front lugs 19 are slid up in the recesses 15 of the shoe and are secured to the shoe by means of the screws 19, as is illustrated in Figs. 1, 3 and 5.

In Fig. 8 I have illustrated a slight modification in the construction of the calk B, in which the calk is made wider than shown in Figs. 5 and 6 and is provided with a shoulder 22 at the rear portion of its upper edge, which shoulder is fitted to the under face of the shoe, thus providing a greater bearing for the calk against the shoe.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. A horseshoe provided with a marginal recess in its under face extending nearly to the ends and provided at its end portions with grooves forming continuations of said recess, a continuous calk extending from end to end of the shoe and engaging the said marginal recess and the said grooves, said calkbeing provided with teeth at its lower edge, and fastening means for the calk.

2. A horseshoe, a calk fitted to the outer marginal portion of said shoe, extending from end to end of the shoe, the said calk being provided with teeth in its lower edge and with openings above the teeth, and means for securing the calk to the body of the shoe.

3. A horseshoe provided with an outer marginal recess in its under face, extending nearly to the ends and provided at its end portions with grooves forming continuations of the said recess, the said shoe being also provided with slots at its end portions which meet the said grooves, a continuous calk which enters the said recess and the said groove, extending from end to end of the shoe, and fastening devices for the calk.

4. The combination with a horseshoe, of a calk which extends continuously from end to end of the shoe, which calk is located at the outer marginal portion of the shoe, said call: having one face tapered from the top downward, the said calk being also provided with series of teeth at its lower end and elongated openings above the teeth, and means for securing the calk to the shoe.

5. The combination with a horseshoe having a marginal recess at its outer edge in its under face, extending to a point near the heel and grooves in the under face at the heel, which grooves form continuations of the said marginal recess, the said shoe being provided with slots in its ends which meet the said grooves and with vertical recesses at each side of the center of the shoe, which meet the said marginal recess, of a calk adapted to extend continuously from end to end of the shoe, said calk being tapered in a downward direction, the upper edge of the calk being fitted in the said recess and in the said grooves of the shoe, lugs extending from the forward portion of the calk, which lugs enterthe forward recesses in the shoe, fastening devices for the said lugs extending into the shoe, and lugs at the end portions of the calk, which end lugs extend up through the end recesses in the shoe, terminating at their'upper portions in forwardly-projecting heads, adapted when the call: is in position on the shoe to extend over the upper face of the shoe at the forward end portions of its end slots.

6. A horseshoe having slots at its end portions, and a marginal calk extending continuouslyfrom end to end of the shoe, the calk being provided with lugs at its end portions adapted to extend through the slots in the ends of the shoe, the said lugs terminating in projecting heads adapted to extend over the upper face of the shoe at the inner ends of said slots.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
